Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to, for example, an earthquake detection illumination device, and more particularly, to an earthquake detection illumination device that can be evacuated safely even during a power failure by continuing to turn on when an earthquake occurs at night.

[0002]

[Prior Art]

 Conventionally, when an earthquake occurs, power failures often occur due to the earthquake. In the event of an earthquake at night or in an enclosed space such as a building, and if a power outage occurs, portable lighting is required to safely evacuate.

A flashlight that is such an illumination is generally one in which the illumination lamp is turned on by manually turning on a switch, and a battery is often used as a power source for illumination.

[0004]

[Problems to be solved by the device]

 However, in the event of a power outage after an earthquake, such as at night, it is necessary to fumble to find the flashlight and turn on the switch.However, due to psychological turmoil, the flashlight cannot be found or the switch operates as expected. In addition to the problem of not being able to do so, when using a flashlight that is not used on a daily basis during evacuation, the battery may already be exhausted and the light intensity may be low, and eventually it may not light.

An object of the present invention is to provide an earthquake detection illuminating device in which lighting is automatically continued without operating a switch when an earthquake occurs and there is no fear of running out of battery immediately after lighting.

[0006]

In order to achieve the above object, the present invention is directed to a power source plug projecting from an apparatus main body, a battery to which a voltage supplied from the plug is constantly charged, and the plug and The battery is equipped with a lighting lamp connected to the battery via a self-holding switch, and the self-holding switch is configured to be always on when the earthquake detection switch is turned on. , The base end is fixed and the free end has a mass, and the supporting system contact is elastically supported in a cantilever state so that the mass rocks when an earthquake occurs, and when the supporting system contact rocks And a ring-shaped contact arranged so as to surround the outside of the support system contact so as to be in contact with it.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view of an earthquake detection illuminating device showing a preferred embodiment of the present invention, and FIG. 2 is an electric circuit diagram of FIG.

The earthquake detection lighting device 1 includes a pedestal 3 (device main body) in which a rectangular circuit panel 2 is housed, an upper cover 4 fitted to the pedestal 3 to cover the circuit panel 2, and a circuit panel 2 Plug 5 for power supply which is connected to the power supply unit and is projected from the lower part of the pedestal 3 toward the rear so as to be plugged into an outlet installed in a general household, and the first and second plugs connected to respective terminals of the plug 5. Line 6a, 6b, a diode 7 and a resistor 8 connected in series to the first line 6a for rectifying an AC voltage, and a charging connected between the first and second lines 6a, 6b. Type battery 9 and seismic detection switch 11 connected in series via main power switch 10 arranged between first and second lines 6a and 6b for opening and closing first line 6a, self-holding Relay 12 (self-holding switch) and The lighting lamp 13 is provided, and the lighting lamp 13 is automatically turned on when the earthquake detection switch 11 detects an earthquake.

One end of the contact 12a of the relay 12 is connected to the first line 6a, and the other end of the contact 12a is connected to the second line via the illumination lamp 13 and the switch 12b of the relay 12 in parallel. ing. Further, one end of the illumination lamp 13 and one end of the switch 12b of the relay 12 are connected to the first line 6a via the earthquake detection switch 11.

The earthquake detection switch 11 includes a support system contact 14 connected to the first line 6a and a ring-shaped contact 15 that comes into contact with the support system contact 14 and turns on when an earthquake occurs. The supporting system contacts 14 are a spring wire 17 elastically supported in the vertical direction in a cantilevered state at the base end with respect to a fixed pin 16 standing upright from the circuit panel 2, and a free end of the spring wire 17. It is composed of a solid mass of lead, etc. that has adhered, and is configured to swing along a horizontal plane when an earthquake occurs. On the other hand, the ring-shaped contact 15 is arranged so as to surround the outside of the middle portion of the spring wire 17 along the horizontal plane so as to come into contact with the support-system contact 14 when it swings. In this case, it is preferable that the elasticity of the spring wire 17 and the gap between the spring wire 17 and the ring-shaped contact 15 are set so as to come into contact with each other and turn on even if an earthquake with a small seismic intensity occurs.

Next, the operation will be described.

In the above configuration, the main power switch 10 is turned off until the plug 5 is inserted into the outlet. When the plug 5 is inserted into the outlet and the main power switch 10 is turned on, the AC voltage introduced from the outlet is constantly charged in the battery 9. Here, in a normal time when no earthquake occurs, the contact 12a of the relay 12 is off and the illumination lamp 13 is off because the spring wire 17 and the ring-shaped contact 15 are not in contact with each other. ing.

When an earthquake having a seismic intensity of a predetermined level or more occurs, the spring wire 17 swings through the outlet, the pedestal 3 and the circuit panel 2 and comes into contact with the ring-shaped contact 15, and the illumination lamp 13 is automatically turned on. At the same time, the switch 12b of the relay 12 is turned on and the contact 12a of the relay 12 is turned on. Once the contact 12a of the relay 12 is turned on, a voltage is supplied from the first line 6a to the switch 12b of the relay 12 via the contact 12a, and as a result, the contact 12a of the relay 12 is always turned on. When the contact 12a of the relay 12 is turned on, a voltage is constantly supplied to the illumination lamp 13 and the lamp 13 continues to light. Even if the earthquake stops after the lighting lamp 13 is turned on, the contact 12a of the relay 12 is always on, so that the lighting lamp 13 continues to be turned on by the voltage supplied from the outlet.

Since the illumination lamp 13 is automatically turned on when an earthquake occurs in this way, even if the earthquake occurs at night or during the day, the illumination lamp 13 can be illuminated when the earthquake occurs. The illuminating device 1 can be easily found with the clue.

After that, when the lighting device 1 is pulled out from the outlet for evacuation, the lighting lamp 13 can be continuously turned on by the voltage charged in the battery 9. In addition, since the battery 9 is constantly charged, the problem that the light intensity of the lamp 13 is low or the lamp 13 is immediately turned off does not occur.

[0017]

[Effect of the device]

 As described above, in the present invention, when the earthquake detection switch is turned on once the earthquake occurs, the self-holding switch is always turned on, and the illumination lamp connected to the outlet or the battery via the self-holding switch is turned on. Since it is configured to continue, the lamp will automatically continue to light without operating the manual switch, and the voltage will continue to be supplied from the battery even if the lamp is pulled out from the outlet, so the lamp will continue to light up Since it is always charged, there is no danger of the battery running out immediately after lighting.
